GAS-LAMP.

provide an improved gas lamp of the inverted burner type in which theparts are accessible for cleaning and adjustment without disassemblingthe lamp.

Further objects, and objects relating to structural details willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the'claims.

A structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanying drawing, forming a part of thisspecification, in which:

Figure I is a side elevation of my improved gas lamp. Fig. II is adetail vertical section on a line corresponding to line 2-2 of Fig. I,the gas supply pipe, burner and valve casing being shown in full lines.Fig. III is a horizontal section on a line corresponding to line 3--3 ofFig. I. Fig. IV is a perspective view of the globe holder, the globeholder member 28 being shown partially open. Fig. V is an enlargeddetail vertical section on a line corresponding to line 5-5 of Fig. III.Fig. VI is an enlarged detail vertical section on a line correspondingto line 66 of Fig. III, showing the arrangement of the globe sections inthe globe holder members 27 and 28. Fig. VII is a detail perspectiveview showing the holder members and the globe sections arranged therein.Fig. VIII is a detail vertical section through the holder members on aline corresponding to line 88 of Fig. VII. Fig. IX is a detail verticalsection on a line corresponding to line 9--9 of Fig. III.

In the drawings, similar reference numerals refer to similar partsthroughout the several views, and the sectional views are Specificationof Letters Patent.

taken looking in the direction of the little arrows atthe ends of thesection lines.

Referring to the drawing, 1 represents the gas supply pipe by which, inthe structure lllustrated, the lamp is supported. The burner comprises aburner tip member 2 and a burner passage member 3. The burner tip memberis provided with burner arms a on which the tips 5 are mounted.

These arms communicate with the central distributing chamber 6.

The passage member 3 has a horizontallydisposed mixing tube or inletpassage arm 7 and a downwardly-projecting delivery nipple 8. This nippleis provided with a flange 9 to which the burner tip member is secured bythe screws 10. The mixing tube 11 is re movable through the inletpassage member 3 and projects into the same beyond the delivery nipplethereof and through the wall or partition 12. The wall 12 is arranged onthe inner side of the delivery nipple 8 and .the gas orcombustiblemixture passes rearwardly over the wall and downwardly to the dischargechamber 6. The air and gas is further mixed in its passage. The passageis curved so that the flow of gas is not materially affected.

- The regulating valve 13 is threaded into the burner passage member 3to coact with the inner end of the mixing tube. The burner passagemember 3 is arranged between the chimney flues 14, a single flue onlybeing shown in Fig. II, and above and in close proximity to thedeflector plate 15. The burner tip member 2 is arranged below the plateand within the skirt portion 16 of the chimney. The burner member 3 isprovided with an upwardly-projecting coupling 17 for the supply pipe 1.The coupling has a laterally projecting arm 18 on which the valve casingis mounted, the valve casing being provided with a nozzle 20 adapted todeliver to the mixing tube. As the valve structure forms no part of mypresent invention, I do not describe the same with further detailherein.

The chimney is connected to the burner by means of the burner tip memberand the screws 10. The deflector plate is extended beyond the skirtportion 16 of the chimney to provide a chimney flange. This chimneyflange has air inlet openings 21 on the outside of the skirt of thechimney. The casing 22 is mounted upon this flange portion of thedeflector plate and projects below the same, see Fig. I. The casing isflared outwardly at its upper end, its lower end being also flaredoutwardly and terminating in an inturned edge. The particular shape ofthe casing is, however, largely a matter of taste. The casing isprovided with air inlet open-- ings 23 above and adjacent to thedeflector plate of the chimney. The air inlet openings oi the mixingtube are within the chimney casin The globe is formed of sections 24,25. These sections are preferably provided with outwardly-projectingflanges at their meeting edges. The globe holder members 27 and 28 areprovided with flanges 29 adapted to receive the flanges 26 of the globesectio-ns. The sections are retained in the holders by means of theflexible fingers 30, which are folded over the edges 01 the globesections. The bottom holder member 28 is hinged at 31 to the upper andis retained in its closed position by means of the hooks 32 on the uppermember which engage pins 33 on the lower. The upper member has a head 35at its lower edge adapted to receive the upper edge of the lower member.

The globe supporting ring 36 is provided with an outwardly projectingflange 37 at its upper edge and is arranged within the portion of thecasing projecting below the chimney flange. The globe supporting ring 36is retained by means of the screws 38 arranged through the chimneycasing to engage the flange 37. The supporting ring projects into theupper edge of the globe and the globe projects into the bottom of thecasing. The air inlet openings 21 in the chimney flange open inside ofthe globe supporting ring so that the secondary supply of air isdirected through the band to the burner. The globe holders are connectedto the supporting ring by the straps 39. By this arrangement of theparts, the lower section of the globe can be opened to afford access tothe burner tips, or to the mantles carried by the mantle plate 40. Asthe mantle plate forms no part of my present invention, I do notdescribe it in detail.

The burner screen is removable through the bottom of the burner, whichis provided with a closure 4:1.

My improved lamp is eflicient and the parts are readily accessible forcleaning or for removal, and the structure is also attractive inappearance.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1.
